Yes...you can add databases and tables via MySQLMan...although your hosting company may have restrictions on the number of actions (Like adding, deleting databases) in their MySQL server. When you install MySQLMan and use it, you should see a list of databases that you have access to, and then you can add tables in those databases.

Keep in mind that some hosting companies only give ONE MySQL database per customer and that you may have to purchase additional databases.
